MODEL FOR PERFORMANCE EVALUATION OF A FLEXIBLE PRODUCTION SYSTEM

The evolution of production systems was mot ivated by two important factors , increasing productivity on one hand and increasing the number of types of products that can be made in the system, on the other hand. When seeking a higher level of automation in the manufacture of products for small and medium series it should be a balan ce between the two conflicting goals , high flexibility and productivity of machinery. A compromise solution offers the concept of a flexible manufacturing system, receiving partial flexible automation. When implementing a FMS the configuration must satisfy both requirements: economic and technical. When implementing a FMS the configuration must satisfy both requirements: economic and technical. The research is oriented towards the study and analysis of these systems in order to know the behavior and perform ance and possible, as well as possible, even before the physical realization. Before evaluating the performance of a flexible production system and deci ding to implement it, are analyze d the specific technical aspects of design, dimension ing and configurat ion. This paper proposes to develop the analytical models for evaluation their performance. Flexible production system is rep resented as a system of network of queues . It can thus calculate, key performance parameters of flexible production system.
